hello,

my amplifier SA-8800 is broken, i've measured and i found that the problem lies on de power amplifier board.
for further investigation and repairing, i need the schematics of the amplifier
anyone who has the schematics, please send it to me.
it is not pleasent when you can't listen to music? :nono:


Thanks

Frederik

Frederikwhat did you measure? do headphones still work ok but not the speakers? are both channels out? if both channels are out i would look at the power supply, if only one channel is out use measurements from the good channel to compare with the bad channel.

They sell them on E-bay. CC

both channels are broken, i measured the incoming signal (after the bias, volume,bass,treble etc) and it was good. when i measured on the power transitor i measured strange incorect signals, so the problem lies between the two, that's why i need the schematics, so i can find the path to the power transistor.

Ps i know i can buy the schematics, but my intension is not to pay 25euros or more for a reparation of maybe 5 euros. :music:

It's also not pleasant for a total stranger to demand something of you that you may have paid for.

Maybe it's just a language thing, but if not you should try some manners.

hello,

yes my mother language is not english, and i am sorry that i sound mayby a little bit demanding, that is not my intension.
i just wanted to be specific, and i am just looking for someone who will share the schematic, if you don't want to share them no problem it is you're choice and i willunderstand it

Hello Frederik, and welcome to AK.

I do not have a schematic for the SA-8800, but I am certain someone here will be able to help you.

Do not worry about the language. We will figure it out.

Doc

I saw your request when you first made it.

I interpeted your request as a request made by someone who spoke another language, and not a demand.

I have checked my files and only found sa-7800 and sa-9500 information.

I did not want to confuse you by posting what I did not have, or wrong information.

But now I must speak, to tell you that you ARE welcome here.

KB9KXH had some good questions and advice that can help you fix the sa-8800.

I'll try to get a e-mail copy out to markthefixer and frederik tommorow night.

Frederik: I need your e-mail address, send me a PM.

Jimmy666: you requested this also, will send tommorow night.

My sa-8800 is not in service at the moment, so if you guys need me to pop the hood and measure something let me know.
